Hela, Queen of the Underworld, is betrayed and brutally killed by Loken, a descendant of a false god. Goddess Freyja turns back time, sending Hela ten years into the past. Hela publicly strips Loken of his privileges, exposes his lie about being her savior, and joins forces with the exiled God of War, Kael. Using a master-servant contract to control Loken as bait, Hela foils the priestly family's conspiracy, rescues the Goddess of Winter, Skadi, and forges a god-slaying blade to face the ancient fire god, Surtr. In the end, Hela and Kael slay the ancient god through their soul resonance, bring an end to Ragnarök, and rule Helheim together.
